Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically to a cooling device for the production of chromium-free passivating agents. Background Technology

[0002] Chromium-free passivating agents can form a dense passivation film on the metal surface through chemical or electrochemical action, preventing oxygen, water, and electrolytes from directly contacting the metal substrate, thereby reducing the corrosion rate. It is an environmentally friendly metal surface treatment agent that replaces traditional chromate passivation technology. It is mainly used to inhibit metal corrosion, improve surface adhesion and weather resistance. The core goal of chromium-free passivating agents is to replace hexavalent chromium with non-toxic or low-toxic components while ensuring the passivation effect of the metal surface. In the production process of chromium-free passivating agents, the synthesis reaction is often exothermic, requiring cooling to maintain a suitable temperature, typically 20-60℃, to avoid component decomposition and film performance degradation caused by high temperatures. Insufficient cooling may lead to polymerization or denaturation of the effective components of the passivating agent, affecting film uniformity and salt spray resistance. Currently, when cooling small and medium-sized reactors used for producing chromium-free passivating agents, circulating cooling water is usually introduced into the reactor jacket to maintain the water temperature at 5-15℃, and the temperature inside the reactor is controlled through heat exchange. Although the above method can cool the chromium-free passivating agent in the reactor, when cooling control is required for multiple reactors in a factory, multiple cooling devices need to be installed in batches, which is inconvenient for simultaneous cooling, occupies a large space, and easily leads to resource waste.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5A cooling device for the production of chromium-free passivating agents includes multiple reactor jackets 1, each with a cooling chamber for storing cooling water. This allows for separate temperature-controlled cooling of multiple portions of chromium-free passivating agent in multiple reactors. The device also includes inlet pipes 2, outlet pipes 3, cooling components, a mounting bracket 4, and a circulation component. Multiple inlet pipes 2 are connected to multiple reactor jackets 1, each equipped with an inlet valve. The outlet pipes 3 are located below each inlet pipe 2 and are connected to the reactor jacket. The jacket 1 is connected, and the water outlet pipe 3 is equipped with a water outlet valve. The cooling component is installed between each water inlet pipe 2 and the adjacent water outlet pipe 3. The fixing frame 4 is located on one side of the multiple reactor jackets 1. The circulation component is installed between the fixing frame 4 and the multiple water inlet pipes 2 and the multiple water outlet pipes 3. Temperature sensors 15 are installed on the multiple reactor jackets 1 to monitor the cooling water temperature in the multiple reactor jackets 1 and to keep the water temperature in the multiple reactor jackets 1 at 5-15℃. At the same time, the temperature sensor 15 is electrically connected to the circulating water pump 6, the water inlet valve and the water outlet valve through the controller.

[0016] refer to Figure 2 as well as Figure 4 The circulation assembly includes a circulating water tank 5, a circulating water pump 6, a support pipe 8, a connecting pipe 9, a circulating outlet pipe 10, and a cooling fan 11. The circulating water tank 5 is installed on one side of a mounting bracket 4. Multiple fixing rods 19 are arrayed on the mounting bracket 4, and all fixing rods 19 are fixedly connected to the circulating water tank 5, allowing for stable installation of the circulating water tank 5 on one side of the mounting bracket 4. A transparent observation window 24 is installed on one side of the circulating water tank 5 to facilitate observation of the cooling water volume inside. A water supply pipe 22 and a drain pipe 23 are connected to the top and bottom of the circulating water tank 5, respectively, facilitating water supply to the circulating water tank 5 and allowing for drainage and cleaning of the circulating water tank 5. Pump 6 is installed at the top of circulating water tank 5, and circulating water pump 6 is connected to circulating water tank 5 by circulating inlet pipe 7. Support pipe 8 is connected between circulating water pump 6 and multiple inlet pipes 2. Connecting pipe 9 is connected between multiple outlet pipes 3. Circulating outlet pipe 10 is connected between connecting pipe 9 and circulating water tank 5. Two cooling fans 11 are provided. The two cooling fans 11 are symmetrically installed on both sides of circulating water tank 5. Two mounting plates 16 are symmetrically connected on the fixing frame 4. Both mounting plates 16 have mounting holes. The two cooling fans 11 are installed in the two mounting holes respectively. The two cooling fans 11 can be stably installed on both sides of the fixing frame 4. When the circulating water pump 6 is started, the cooling water in the circulating water tank 5 enters the multiple reactor jackets 1 through the support pipe 8 and multiple inlet pipes 2. At the same time, the cooling water in the multiple reactor jackets 1 can enter the circulating water tank 5 through the connecting pipe 9 and multiple outlet pipes 3. Meanwhile, the two cooling fans 11 can blow air onto the surface of the circulating water tank 5 to accelerate the airflow around the circulating water tank and accelerate the dissipation of heat. Thus, the cooling water in the circulating water tank 5 can be circulated and cooled. At the same time, the cooling water in the multiple reactor jackets 1 can be circulated and cooled through the support pipe 8, connecting pipe 9, multiple inlet pipes 2 and multiple outlet pipes 3. Thus, the chromium-free passivating agent in the multiple reactors can be circulated and cooled to maintain a suitable temperature for the chromium-free passivating agent in the multiple reactors.

[0017] refer to Figure 2 , Figure 3 as well as Figure 4 The cooling assembly includes a cooling cylinder 12, cooling pipes 13, and cooling fans 14. The cooling cylinder 12 is detachably connected to the adjacent reactor jacket 1, and an exhaust port is provided on the cooling cylinder 12. The cooling pipes 13 are located inside the cooling cylinder 12 and are connected between the inlet pipe 2 and the outlet pipe 3. Multiple cooling valves are installed on the multiple cooling pipes 13 respectively. Multiple temperature sensors 15 are electrically connected to the multiple cooling valves and multiple cooling fans 14 through a controller. The controller can start the multiple cooling valves and multiple cooling fans 14 respectively. There are two cooling fans 14, which are symmetrically installed through the cooling cylinder 12. Multiple mounting blocks 20 are fixedly connected to the cooling cylinder 12. Each mounting block 20 is threadedly connected to the adjacent reactor jacket 1 with mounting screws 21. By turning the mounting screws 21 between the reactor jacket 1 and the multiple mounting blocks 20, the cooling cylinder 12 can be installed and removed on the reactor jacket 1, thereby allowing the cooling pipes 13 and cooling fans 14 to be removed and replaced. When the temperature sensor 15 detects that the cooling water temperature in the corresponding reactor jacket 1 is too high, it will close the adjacent inlet and outlet valves and open the cooling valve, so that the cooling water in the reactor jacket 1 circulates in the cooling pipe 13, inlet pipe 2 and outlet pipe 3. At the same time, the two cooling fans 14 are turned on, so that the two cooling fans 14 can blow air onto the cooling pipe 13, part of the inlet pipe 2 and part of the outlet pipe 3, accelerate the air flow around the cooling pipe 13 to accelerate the heat dissipation, thereby cooling the cooling water between the reactor jacket 1, cooling pipe 13, inlet pipe 2 and outlet pipe 3, and thus controlling the temperature of the chromium-free passivating agent in the corresponding reactor.

[0018] refer to Figure 1 as well as Figure 2Two support rods 17 are symmetrically connected to the top of the circulating water tank 5. Support blocks 18 are fixedly connected to both support rods 17. Support ports matching support pipes 8 are opened on the support blocks 18. The two support rods 17 can stably support the two support blocks 18, and the two support blocks 18 and the two support openings can stably support both sides of the support tube 8, thus improving the stability of the support tube 8 during use.

[0019] In summary, the cooling device for the production of chromium-free passivating agent first starts the circulating water pump 6, allowing the cooling water in the circulating water tank 5 to enter multiple reactor jackets 1 through the support pipe 8 and multiple inlet pipes 2. Simultaneously, the cooling water in the multiple reactor jackets 1 enters the circulating water tank 5 through the connecting pipe 9 and multiple outlet pipes 3 for recycling. This allows for the circulating cooling and flow of the cooling water in the multiple reactor jackets 1, and also for the circulating cooling of the chromium-free passivating agent in the multiple reactors, maintaining the chromium-free passivating agent in the multiple reactors at a suitable temperature. When a temperature sensor 15 detects that the cooling water temperature in the corresponding reactor jacket 1 is too high, it sends an electrical signal to the controller, causing the controller to close the corresponding inlet and outlet valves, and simultaneously open the corresponding cooling valve and cooling fan 14. This allows the two adjacent cooling fans 14 to blow air onto the cooling pipe 13 for cooling, thereby circulating and cooling the adjacent cooling pipe 13, inlet pipe 2, outlet pipe 3, and cooling water in the reactor jacket 1, and thus lowering the temperature of the chromium-free passivating agent in the corresponding reactor.
